What do you use and where did you get it

I have some wire racking that hold plates and bowls and such vertically. I got them from the previous owner of my motorhome, who left it in place. The plates etc. are rubbermaid plastic or similar, so there's no concern of them breaking if they do jar loose. Glasses are just stacked up in the cupboards, and are also plastic, the sort of ones sold for picnic/patio use.

I'm still trying to find some halfway decent nonbreakable cups/mugs that don't cost a fortune. The closest I've found to what I'd like are various ones sold for food service use, but they seem to only be sold in cases of a dozen or more.
